Just bought a citizen with 8200A and I really appreciate your teardown. Its informative and it is quite peaceful to watch (pun intended). These really are beautiful pieces of mechanics
It is a very solid watch and can stand the test of time (pardon the pun). I like it as it has that vintagey and lux vibe it exudes. If you squint, you can see a hint of Universal Geneve Pole Router. Thanks for viewing my channel and leaving your comments.
Thank you. I have just purchased an 8200 so that I can do as you suggested. 'Lockdown Take up watch repair'. Spent hours on videos. Yours is excellent. Now is the time. Wish me luck. I do have a few questions for you. You said you were going to disassemble, and clean. What cleaning system do you use? Just an Ultrasound? If you do, can you show its use please. What oil do you use? Thank you
Thank you so much for liking the video. Good luck in your watch repair journey. It is very addictive and can really test one's patience. Best tip that I can give is never to force any part that don't want to budge or spin. Understand first why it won't give otherwise you might end up ruining a part. . . As for cleaning, I've been using a small ultrasound and played around with several techniques and solvents until I could find one that gave me the best results. What I ended up using are products by L&R and with a three bottle approach. I should create a video specifically focussing on my cleaning method so stay tuned. . . In the oiling department, I've been using Moebius products: - D5 for all jewels and posts - 9501 keyless works - 9010 end cap jewels, escape wheel and fourth wheel - 9415 pallet jewel . . Again, good luck and most of all, have fun!!
great video. I have a 2010 citizen dive watch with this movement with very little use. I changed the crystal to sapphire, but broke the stem when i took the movement out. I had to remove the back plate to get the short piece of stem out and replaced with a new stem have crown attached properly. I Put all wheels back seems to line up ok after a few attempts but had some doubts about 3rd and 4th wheel. After screwing plate down, i'm able to wind the crown and spring , but it wont start/tick, i can feel the resistance on the spring, but not sure why its not releasing power to the balance and escape wheel which are not moving . i don't know if there's a problem with the 3rd or 4th wheel - would that explain no power transmission??. Im quite sure I have them in the correct position and correct side down looking at your disassembly. Only damage so far I did slightly bend the "friction spring for sweep second pinion" and straightenend it back would this affect anything? thanks, this is learning for me, i really like the watch but not worth paying quite a lot to correct probably fairly simple issue of proper assembly .
Thanks for watching the video. Sounds like there’s a problem with the train of wheels. Maybe try removing the balance complete and pallet fork then try winding some power and see if it spins freely. It could be the pivots too. Hope that helps. Thanks again.
Without knowing the state and provenance of the watch, it could be a lot of things. It's possible the pivot holes have dried up oil so it puts unnecessary resistance to the train wheels thereby stopping the movement eventually. It could be the mainspring being tired and old. Best to have it serviced by your nearest local watch repairer. Thanks for watching.
Hello, I have a question to see if you can give me a hand, I have a citizen 7 eagle with the same movement (8200a), but it has been kept for a year and a half, I sold it yesterday and the buyer tells me that the watch has stopped for 3 sometimes even wearing it on the wrist...do you think that due to the time it has been stored it should be charged longer or perhaps it needs maintenance (lubrication)...what do you recommend, regards.
Great question. First reaction would be crusty oils? If it's been sitting for quite a while and haven't been serviced that could be the issue. Can you manually wind the watch until it's fully wound? If so, does it or will it stop mid-way while unwinding itself in time? If it doesn't then maybe the rotor isn't doing it's auto-winding job so the watch runs out of power. If it stops even when fully wound then it could be the dried up oils, dodgy pivots and maybe some missing teeth in the train wheels. Hope that helps. Thanks for watching.
@@artoftinker3713 Thank you for your prompt response. I have had many watches, battery, quartz, and winding, but the first is automatic, the Miyota 8200, and I am not sure how to wind it manually, since when I bought it, I kept it right away and 2-3 times when I bought it. I took it out of its box, it only updated the time and immediately the second began to work, there is very little information on the web about how to wind this model with a screw-down crown, some say that it is forward with the crown closed, others that backwards, others that You have to remove the crown, etc., 10 turns, 40 turns, etc... do you know the correct way to wind this miyota 8200a movement? ... thanks
@@falomore my one isn't a screw-down crown so to wind it, I had to turn it forward, away from yourself, for about 30 turns. Looking at it in a different way, if you're facing the crown from the side, then it will have to be wound clockwise.
Hi. Thanks for stopping by. I believe the 8200 has a single-piece rotor weight whilst the 8200A has a two-piece riveted one. Why they did it that way, I have no idea. Aside from that everything else I think are the same. Although, some say the 8200 isn't hackable and 8200A is. Can't confirm though. Thank you so much. :)
@@Recreantx Good question. Honestly, I don't know. You'd think it would be interchangeable as they're nearly the same movement, but I'm not really sure. Perhaps some of the subscribers or viewers might know? Anyone?
Thanks for the tip. As the watch is dirty and will be heading for the cleaners, finger cots or gloves aren't necessary. For a cleaned movement and ready for re-assembly, yeah, I would. Cheers.
